    Finally had a chance to test it!

    Purchased this about 5 months ago and have just had the ‘opportunity’ to actually test it’s jump starting capability. Obviously very compact and clearly a great high capacity USB power bank. BUT, the only reason anyone buys this is for the jump start function. IT WORKS! A neighbor had a TOTALLY depleted battery on a 3.5 liter Subaru. Although well below the 7.5L advertised capacity, any dead battery makes for a good test. INSTANT START after connecting. Easy, flawless, as advertised.

    It works when you need it.

    I bought this two years ago. I charged it and put it in the car. Today, two years later, a motorist needed help to jump start his car. It took me less than 10 seconds to unpack and hook up and get him started. Buy with confidence.

    This thing is a miracle worker

    My car constantly drains my battery, which has left my battery completely shot. I have to jump my car with this almost every time and it always cranks it right up with no issues. I’m so glad that jump packs are no longer those giant battery packs that weigh a ton.

    Easy to use

    The jumper starter is relatively light and compact. It has a very large LCD screen which is bright and easy to read. It charges fast, I connect it to my almost dead car battery and it takes less than 5 mins to be 100%. So simple to use. Problem solved. I would recommend it to my friends.

    Reliable and good idea.

    I was just testing of 5V input is good, you need this only if your battery is completely dead. Typically (99%) we will have discharged battery condition happens if we forgot turn off lights of car or missed to close the door/trunk properly… Or old battery that is not able to start the car. In these these jump start works like charm in that case. the good thing is this is supercapacitor design and battery-free solution. Just leave in our car like jump start cable and never worry about charging. If you run in to dead battery situation, you have the savior. I got one for my CRV.

    The device work fine however it is poorly built. On first use the power button fell inside the device on is there. The button felt very inferior. Equally the positive clamp fell apart. I was able to put it back together. A useful device but over priced for its quality.
